Encouraging words from friends and family can pave the way to sporting victory, according to research by the University of Exeter, released today. Dame Kelly Holmes and Sir Chris Hoy have both cited the ongoing support of their families and friends as a major factor in their Olympic success. Now, for the first time, this study quantifies the benefit of this kind of support on sports performance. http://www.physorg.com/news155305708.html Other Sciences Tue, 03 Mar 2009 12:29:03 EST news155305708 A team of scientists, led by the University of Exeter, has used game theory to explain the bizarre behaviour of a group of ravens. Juvenile birds from a roost in North Wales have been observed adopting the unusual strategy of foraging for food in 'gangs'. New research, published in the journal PLoS One (on Wednesday 25 February 2009), explains how this curious behaviour can be predicted by adapting models more commonly used by economists to analyse financial trends. http://www.physorg.com/news154767795.html Other Sciences Wed, 25 Feb 2009 07:03:52 EST news154767795 Scare tactics may not be necessary when trying to get patients at risk of heart disease to change their diet or behaviour, a new study has found. Instead, doctors and nurses should be aware of the stage of life their patients are at, and offer them very specific and targeted advice. http://www.physorg.com/news154615288.html Medicine & Health Mon, 23 Feb 2009 12:42:06 EST news154615288 Research from the University of Exeter reveals for the first time, that changes in brain activity, triggered by physical exercise, may help reduce cigarette cravings. Published in the journal Psychopharmacology, the study shows how exercise changes the way the brain processes information among smokers, thereby reducing their cravings for nicotine. For the first time, researchers used functional Magnetic Resonance Imaging (fMRI) to investigate how the brain processes images of cigarettes after exercise. http://www.physorg.com/news153482201.html Medicine & Health Tue, 10 Feb 2009 09:57:05 EST news153482201 (PhysOrg.com) -- Shopping locally may not be as good for the environment as having food delivered, according to new research by the University of Exeter (UK). Published in the journal Food Policy, the study shows that, on average, lower carbon emissions result from delivering a vegetable box than making a trip to a local farm shop. http://www.physorg.com/news152795735.html Other Sciences Mon, 02 Feb 2009 11:17:29 EST news152795735 Research published today reveals the major influence of fish on maintaining the delicate pH balance of our oceans, vital for the health of coral reefs and other marine life. http://www.physorg.com/news151251557.html Space & Earth Thu, 15 Jan 2009 14:19:17 EST news151251557 Females of all ages are less active than their male peers. Two studies, presented today (Tuesday 6 January) at a major academic conference, reveal the gender difference in activity levels among school children and the over 70s. Both studies show males to be more physically active than females. http://www.physorg.com/news150446607.html Medicine & Health Tue, 06 Jan 2009 06:43:27 EST news150446607
